I have had this exact problem everytime I try to check in for a flight for the last year and a half, at least. I doesn't matter if I try to check in (hit the retrieve reservation button) 1 second after the 24 hours starts, or 10 seconds or 10 minutes, I get the message below. (photo is also attached). I hit OK, try again and get the same message. I hit OK, and then the 3rd time I try to check in it lets me. The problem is by now you have moved down the A and B boarding position 'food chain' quite a bit. Any help or ideas welcome. It must be a problem with my phone as I can check in from another iPhone (same model with same IOS) no problem. Sorry! We can't check you into this flight. Please see a gate agent.
